Denver, the second-best team in its conference, suddenly loses its coach midseason due to scary health reasons.What's next is a cautionary tale.See, this didn't just happen to this season's Broncos, it also happened to the 201...

I'm curious to hear if they are going to tweak the roles of the defensive assistants to delegate more tasks off of Del Rio's plate. His game-time role as defensive play caller is crucial but no doubt the DC has many more mundane tasks that could be handled by an assistant.

They might also want a backup plan during the games that would allow an assistant to "wear the DC hat" for a brief interval if something critical happens on the head coaching front.
